| Summary: | In this work, we have investigated the potential of zigzag phosphorene antidot nanoribbons (ZPANRs) for biosensing applications. ZPANRs were created from the optimized structures of phosphorene nanoribbons by using a density functional theory tool. Utilizing the generalized gradient approximation half method for improving the accuracy of calculations, we have studied the electronic and sensing behavior of ZPANRs based devices wherein nucleobases were inserted into the device. We have compared the device performance of ZPANRs with and without nucleobases and found that using ZPANRs devices, we are able to identify different nucleobases with considerable sensitivity. In a quantitative manner, a max sensitivity of 45 % is achieved while identifying adenine nucleobase using the ZPANRs based devices. From these simulation results, it is predicted that the ZPANR based two-terminal device can work as a possible biosensor. |
